sorry to say, but nope. won’t fit. in fact, if i’m not mistaken, a B16 head and a B18C head have different bolt patterns, so THOSE aren’t interchangable either.

well, the PR3 type-R head is the same as a b16 head (both are PR3 casting)
but the GSR/SIR P72 head has a different manifold bolt pattern than the PR3 head.

either way, any manifold designed for a VTEC head will not mate to a non-vtec head.

u can re-drill it. i had a re-drilled b18c1 victor x manifold to fit a pr3 head. if u re-drill the flange to line up with the pr4 head, and the ports line up, ur good.
